I have a 2004 Bounder 38N (DP)with Michelin 255/80R 22.5 tires I have about 24K miles on it now. I was checking the tire pressure and noticed the right rear (outer) looked like it was wearing more than the others. A closer look revealed the inside tire was worn completely through the grooves on all but the three center groves. It's also flat (although the rig's on its jacks the tire looks ok because its off the ground). The left rears have at least 3/8" of tread and are wearing evenly.
The manufacturing date on the tires is 2403 so there not quite five years old.
Any ideas as to why the right rears could wear faster than the others? Could wheels, shocks or something else be a problem?
I will probably replace all six by next spring but I'd like to know what could have caused this so I could get it fixed.

First reaction is that the right rear outer has been carrying all the weight because the right rear inner has been flat.

Could be loose or bad wheel bearing allowing the wheel assembly to run at an angle.

Sounds like you drove it with not enough air in it. The inside of the tire being not worn is confirmation. Then the other tire wore more to make up for the inside being under pressured. I would replace both, perhaps with the fronts and put new ones on front. They are about $325 each.

Underinflation will cause this problem. The tire wears more on it's sidewalls, while the center of the tread does not have much pressure between it and the road.
Overinflation causes the center of the tire to wear out faster (it is inflated like a balloon, causing the weight to be supported more by the center of the tire than the edges of the tire).
You probably picked up a nail or something about 200 miles before parking the RV, and it has been under inflated for some time. Now you are reading the pressure as around 0 PSI. You might be able to repair the tire and use it some more, but when they remove the tire from the rim they might find it is totally damaged. They will probaly also find the outside tire is damaged from running overloaded for that 200 - 400 miles you drove with a underinflated inside rear tire.
If you still need to be convinced to replace both tires, take a string and wrap it around one of the tires before they install them. See if both tires are the same lenght string. If one is 1/4" longer than the other, then the two tires will be turning at different speeds (until one blows out) because one will be turning at say 500 Revolutions per mile while the other is turning at 502 RPM. Because they are mounted together, one will get pulled along and the other pushed along until one fails.
However if both tires look fine on the inside, then you are good to go camping with your current tires.
I think your tires are about $600 each, so it is better to make sure you need one rather than say get two new ones. Although you can keep the best looking tire as a un-mounted spare tire.
Some tire shops will send a truck out to retrive your tires. Sometime big rigs are serviced on the side of the road (actually it is very common) so a tire shop might send out a rig to your RV. If you are parked in a RV park, you will need approval for this. Otherwise I know someone with a RV your size and they installed new tires right in his front yard.
It is better to patch a RV tire rather than plug a hole when you get a nail in the tire. (they can also inspect for sidewall damage when the tire is off being patched) Also you want metal tire inflation extenders so you can fill the rear tires without add-on extenters that can leak. What they do is install 8" long inflation valve that has a 180 degree curve in it, so it extends to the outside. They don't leak.

Good point! My last trip was down the I 5 from Oregon and don't remember checking the air each morning(too much of a hurry). I may have picked up something and not noticed it.

Did you notice the rig rocking side to side while in motion? That could happen if one dual is low or flat.

I think that was more information than we needed to know....
